GAS-EXPANSION CHAMBER FOR TORPEDO-BOATS.

SPECIFICATION forming part of Letters-Patent No. 250,144, dated November 29, 1881.

, Application filed October 17, 1851.

To alt whom tt may concern Be it known that I, GEORGE E. Hnreu'r, of Hartford, in the county of Hartford and' State of Connecticut, have invented certain new and useful Improvements in`Expauders for Torpedo-Boats; and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use 'the same, reference bel laskor receptacle of great strength, which contalus the condensed gas undera very high pressure, being generally under sufficient pressureto bein aliquid form. This is allowed to escape from the Vflask as required for the engine, and upon being relieved from a part of the pressure suddenly expands to many times its former volume, and is then used in the engine. The gas in. expanding develops a great degree of cold by abstracting heat from surrounding objects, and thus sometimes freezes the liquid remaining in the flask, and the gas also rcqnires to have a large amount ot heat supplied to it in order to bring it up to a temperature at which it can be eiliciently used in the engine. v

The object 'ol' my invention is to provide a more efficient mechanism than has heretofore been in use for the .purpose of raising the temperature bt' the gas by means of heat dcrived from the water through which the bout passes.

In the accompanying drawings, illustrating my invention, Figure l shows a side view ot' a torpedo-boat Afurnished with my improvement. Fig. 2 shows a cross-section through the eylindrical part of the hull, with the interior parts not relating' to my invention omitted. Fig. 3

' shows a top view of the-lower halt' of the part ofthe hull containing my improvement, with gine.

a portion in. the middle cut out, so as to show (No model.)-

the Vessential portions ou a larger scale, the scale of Figs. 2 and 3 being the same.

A is the ordinary exterior shell of a'torpedoboat.

B and B are two semi-cylindrical metallic shells, bolted together at their edges, the upper one of which is intended to tit close tothe shell of the be? t, and the other slightly separated from it, so as to leave a space between them. The ends of the lower shell are curved upward to meet the inner one, as shown in Fig. 1, thus entirely'inclosing the space between them. y

C C'are partitions between the two shells B B', extending from one end nearly tothe other.

The partitions C commence at the upper end, as shown in Fig. 3, and extend nearly .to the lower end, and the partitions C commence' at the lower end, as shown in the same ligure,

and extend nearly to the upper end. These partitions are held in place by bolts or 'rivets passing through the two shells, as shown in the drawings. This arrangement makes a continuous channel, D,Vfrom side to side of the boat.

'E is the inlet-pipe from the'gas reservoh` or ilask, through which the liquid condensed gas is admitted by a suitable cool; in the desired quantity to propel the engine.

Fis the outlet-pipe,throughwhich the heated gas, expanded to its full volume, passes to the engine.

The gas, in passin'g from E to l", traverses a long distance through the channel l), moving in the direction of the arrows, and has a large surface exposed to the action ot' the sea-water through the plate B, by which its temperature is raised nearly or quite to that o t' the surrounding water, which is constantly replaced by the boat passing through it. By thismeans a much greaterellitiency` is obtained from the same amount oi" gas than by the ordinary methods otoonveying the gus to the en- This result is also obtained without materially increasing the resistance ot' the boat moving through the water or requiring any irregular projections from the hull.

My improved expander can be attached to the ordinary shell ofthe boat hy means of the `5 What I claim as my' invention is-,
